Standards for describing learning items on a LMS

We are due to launch an LMS in July and are looking at producing some standards on how to describe learning content i.e. formal courses, online learning on the LMS.

Are there any standards or best practice guidelines that anyone can share on how to describe learning items?

Many thanks
